Hydraulic Diversion Tunnel Longitudinal Section for Suoi Chan 2
Comprehensive longitudinal section of a hydroelectric diversion tunnel for the Suoi Chan 2 Hydropower Project, depicting tunnel alignment, rock classification, and lining details spanning 1587.515m. The tunnel features multiple cross-sections (Types A, AB1, AB2, B, C, and D) corresponding to surrounding rock classifications (II-V), with specifications for concrete lining (M200/C20), shotcrete applications (10cm thickness), and reinforcement systems. Key elements include:
Tunnel Parameters
– Total length: 1587.515m with chainage markers throughout
– Tunnel profile: 9.0m² cross-sectional area
– Gradient variations: 0.22% to 3.0%
– Direction changes: N15°11’1″E, N35°0’8″E
Rock Classification & Support
– Type II rock: Section A/AB1 lining with shotcrete and rock bolts
– Type III rock: Section B/AB2 lining with reinforced concrete
– Type IV/V rock: Sections C/D with heavier reinforcement
Includes a surge tank connection, vehicle turning areas, and specifications for grouting, hardcore beds, and waterproofing. Working water levels range from minimum 117.80m to maximum 139.00m, with dam elevation details and pressure pipe connection specifications.
